ECDHE
Abbreviation for Elliptic Curve Diffie-Hellman Ephemeral
In short and in plain language
ECDHE is a method for encrypted connections.
With it, the browser and server agree on a shared key. This happens when the connection is set up.
Each connection gets a new key that lasts only a short time.
It is a common part of a current setup for secure connections.
